[Freeipa-users] Allow user or group to switch user without password and not becoming root

[Gould, Joshua]

For the NOPASSWD option, I found that using !authenticate  in the sudo option is what IPA wants instead.


$ ipa sudorule-add-option readfiles
Sudo Option: !authenticate
-----------------------------------------------------
Added option "!authenticate" to Sudo rule "readfiles"
-----------------------------------------------------

Hello Team,

We have RHEL 7.1 and IPA server 4.1.0 in our environment as well as stack of Oracle software that require existence of local passwordless users like weblogic and oracle.
Users log in to servers via domain accounts at IPA server.

I’m trying to configure Sudo policy in IPA server that will allow users in the company to log in to servers in IPA domain and switch to weblogic or oracle user without having to enter any passwords, but also without increasing their privileges to root.
Using plain /etc/sudoers file it can be accomplished something like below:

%users ALL = (root)

Users will be who of the IPA sudo rule

NOPASSWD:

This will be an option that you would put into the sudo rule

/bin/su – oracle

This will be the command. You create a command and then reference it in the rule.

At least this is what I would try.


How can I configure this behavior in IPA server?

Regards,

Andrey
